MACHINERY FOR CLEANING AND POLISHING SHEET METAL.

SPECIFICATION forming part of Letters Patent No. 225,796, dated March 23, 1880.

Application filed October 13, 1877.

To all whom it may concern:

Be it known that I, WALLACE H. CAMP, of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Machinery for Cleaning and Polishing Sheet Metal, 850., of which the following is a description.

My invention consists in the combination, with a series of cleaning or polishing rollers supported in fixed bearings, of a gravitating cleaning or polishing roller or series of rollers arranged in position intermediately between the first said rollers, and supported in a frame and links or radius-bars connected to said frame, whereby the latter may be raised, so as to move the gravitatin g roller or rollers in arcs above the first said rollers, to permit the metal to be polished to be introduced between them.

In the accompanying drawings, Figure 1 is a side View of a machine embodying my invention. Fig. 2 is a central longitudinal section thereof; and Fig. 3 is a transverse section of the same, taken on the plane of the dotted line or m, Fig. 2.

Similar letters of reference designate corresponding parts in all the figures.

The frame A of the machine may be of any suitable form.

B designates a series of polishing or cleaning rollers supported in fixed hearings in the frame A, and C designates a series of gravitating polishing or cleaning rollers arranged in position intermediately between and above the former, and preferably so that they may be raised to facilitate the introduction of the metal, S, to be polished or cleaned by them. These rollers may be of any suitable number, and may be faced or covered with any suitable polishing or cleaning material.

The gravitating rollers C may be connected with the main frame of the machine in any suitable manner, and either separately or together. I have shown them as all arranged in a frame, D, connected by links or radius-bars E to'the main frame A of the machine, and capable of receiving a weight, if desirable. It is advantageous thus to combine them with the rollers'B, because they may be swung above the rollers B, as indicated by the dotted lines in Fig. 1, and the metal to be cleaned, inasmuch as it may be passed between the two series of rollers without bending, can be introduced easily. These rollers O bear upon the metal with forcedue to their weight, or weight placed upon their frame, and as their weight or pressure increases they descend between or toward the sides of the rollers B, thereby acting with a greater extent of surface upon the metal and with greater effect, as may be readily understood by referring to Fig. 2.

The metal to be subjected to the two series of rollers is intended to be drawn or fed along in the opposite direction to that in which the said rollers rotate, as indicated by the arrows in Fig. 2, and this may be efi'ected in various ways for instance, .by a suitably-rotating feed or delivery roll or drum, F.

Motion may be imparted to the polishing or cleaning rollers and the feed or delivery roll or drum in any desirable manner. I have shown it as derived from a pulley, G, and transmitted thence through a gear-wheel, H, on the driver-shaft, whereon said pulley is mounted, to a'gear-wheel, I, on the feed or delivery roll or drum, and likewise to a gear-wheel, J, 011 a shaft, K. From thisshaft K the motion is transmitted to a gear-wheel, L, on a shaft, M, and thence to small gear-wheels Non the polishing or cleaning rollers B. The gear-wheels N, engaging with corresponding gear-wheels O 011 the gravitating rollers C, transmit motion to these rollers, and as the points at which the links or radius-bars E are connected to the main frame A and frame D are the same distance apart as the centers of the two series of polishing or cleaning rollers B G, the gearwheels N 0 of these rollers are always in gear.

It will be seen that by my invention I produce a machine which, because of the gravitating polishing or cleaning rollers, is very efiective, and which, because of the facility afforded for raising said rollers above their fellows and permitting the insertion of the metal to be polished or cleaned, is very convenient.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with a series of cleaning 2 seat ac or polishing rollers, B, supported in fixed bearings, of one or more gravitating cleaning or polishing rollers, 0, arranged in position intermediately between the rollers B, and supported in hearings in the frame D, and the Witnesses: radius links or bars E, connected to said frame, l E. D. KETGHAM, whereby the latter may be raised so as to I M. L. SPERRY.

move the gravitating roller or rollers in arcs above the first said rollers, substantially as specified.
